How a Heat Pump Cools Your Residence

In the U.S., heat pumps can be a popular choice to heat and cool your house. 

They seem about the same as an air conditioner. In reality, they operate in a similar fashion during hot weather. Due to a reversing valve, they can transfer warmth in the opposite direction as well as heat your residence when temperatures drop. 

Not sure if you have a heat pump or an air conditioner? Just track down the model number on the outdoor unit and run it online. If you find you own a heat pump, or you’re thinking about purchasing one, learn more about how this HVAC equipment keeps homes cozy. 

How Heat Pumps Operate 

Heat pumps use a refrigeration system much like an air conditioner. Most can run akin to a ductless mini-split, because they can heat and cool. Heat pumps use an indoor evaporator coil and an outdoor condensing coil. Refrigerant is pumped through these coils to move humidity. The outdoor unit also uses a compressor and is enclosed by metal fins that work as a heat sink to help move heat efficiently. 

Summertime Cooling 

In cooling mode, the refrigerant begins in the evaporator coil. Air from within the house is distributed over the coil, and the refrigerant removes heat. Water in the air also condenses on the coil, dripping into the condensate pan below and drains away. The resulting dehumidified air circulates through the ductwork and back into your house. 

At the same time, the refrigerant passes through a compressor on its way to the outdoor coil. This constricts the refrigerant, causing it to get hotter. As it moves through the condensing coil, the outside fan and metal fins help to discharge heat to the outside. The refrigerant travels back indoors, moving through an expansion valve that chills it considerably, preparing it to go through the process from the beginning. 

When your heat pump is installed and maintained correctly, you’ll enjoy efficient cooling comparable to an energy-saving air conditioner. 

Wintertime Heating 

When your heat pump is set to heat, the heat exchange process occurs in reverse. By flowing in a different direction, refrigerant extracts heat from the outdoor air and adds it into your home to warm the inside. 

Heat pumps working in heating mode are most effective when the temperature is warmer than freezing outside. If it gets too frigid, a backup electric resistance heater starts to keep your residence comfortable, but your heating expenses increase as a result. 

Heat pumps are on longer than furnaces because the air doesn’t become as warm. This helps sustain a more even indoor temperature. Additionally, because heat pumps move heat rather than creating it from a fuel source, they can perform well above 100% efficiency. You should expect 30–40% savings on your heating bills by using a heat pump.
